Cladding panel

ABSTRACT

A cladding panel comprising a top multi-film layer and a base layer configured for connection to a substrate, the top multi-film layer including at least an external substantially transparent film and a granular film adjacent to the external substantially transparent film. Disclosed are also methods of producing the cladding panel and kits of cladding panels.

FIELD OF THE INVENTION

The field of this invention relates to cladding material constructions and, more particular, to cladding panels and modules for decoration and/or insulation of structures such as buildings and houses.

BACKGROUND OF THE INVENTION

The most common materials, for insulate the walls and the roofs of a house, are rigid foam (polystyrene or polyurethane), or wool (made form fiberglass or rock). Those materials are typically light, with a high insulation power (their R-value per inch is between 3.2 and 7.2). However, because of their softness and permeability, these materials need protection: this is why in a building they are found inside the walls or in the attic. The insulation process is relatively easy to execute during the construction of the building; unfortunately, the insulation process may not be as easy for an already constructed house with a solid bricks or stones finishing, which needs to improve its insulation.

A solution, in this case, is to insulate the exterior surface of the wall with rigid foam and then protecting it with vinyl siding or stucco (EIFS system) giving up at the aesthetic finishing of the existing façade. Another solution to protect the insulation and at the same time have a similar finishing is building an additional wall in order to support the weight of the new installation (made of bricks or stones).

In the last decades, stone veneer became another alternative protection and finishing of the insulation made of rigid foam installed on exterior wall of the house. Made from concrete and colored with iron oxide, this product is less heavy and easier to work with than real stone or brick; it can be installed, after a proper preparation, directly on the rigid insulation and the appeal, look like real.

Another solution is using polyurethane panels (faux stone) with the appeal of bricks or stones assembled and grouted. This product, differently from the previously mentioned stone veneer, has insulation power, albeit low due its high density in order to increase his mechanical resistance.

However, all the previously mentioned products and materials have strong limitations: Built on site EIFS System:

-   -   It can crack: 1. when is made manually on site, the thickness of         the coating is not even causing different shrinks; 2. when made         under extreme whether condition; 3. The system itself can hold         just some but not all of the natural movement of the building         being insulated; 4.

Because the exterior surface is permeable, the moister, trapped inside the coating, will eventually turn in ice in the winter, and deteriorate the insulation property.

-   -   The color fades because of the UV effect     -   It can't hold any weight except with some precautions     -   Patches or additions will be always noticeable

Pre-Fabricated System EIFS:

-   -   The exterior finishing, made in panels, shows seam where the         panels join     -   Variation of finishing just in the color

Stones End Brick:

-   -   Because of their weight, transportation and handling require         excessive time and is expensive     -   Brick absorbs moister causing crumbling over the years     -   Have to be installed and cut one by one     -   Experts to layer breaks are not easy to find     -   Stone quarries are not everywhere     -   not earthquake-proof

Stone Veneer:

-   -   They can be installed directly on the rigid insulation, but         because of the weight of the stone veneer, the insulation board         surface needs to be reinforced adding to the cost and time of         labor     -   The color is superficial. If cut or accidentally chipped will         show the material of which are made: concrete     -   Because of its porosity, the concrete absorbs and transfers         moisture to the insulation     -   Not earthquake-proof

Polyurethane Panels (Faux Stone)

-   -   The color is superficial. If cut or accidentally chipped will         show the material of which are made: polyurethane     -   Easy to scratch     -   Their look is poor (i.e. poor aesthetics)     -   Because are made in panels they need to be cut in order to get         the desired dimension in proximity of the corners, leaving a         visible straight vertical seam and a non-continuity in the         finishing.

Perhaps with the exception of the polyurethane panel, the other materials mentioned above require skilled labor.

Technical Problem

The demand of performance products capable to overcome the above problems and limitations has prompted the industry of insulation system and of artificial stones to develop system of insulation with new concepts. The obstacle to overcome is represented by the need to give to a “soft” material, such as polystyrene or polyurethane, hardness, beauty and durability like the finest materials of marble or stone. U.S. Pat. No. 8,806,838 discloses a stone plate attached to a front surface of the insulating board; and a reinforcing board attached to a rear surface of the insulating board where brackets will connect, said stone plate, said insulating board and said reinforcing board, to the wall. However, the above technology has several limitations. A limit in the finishing, because of the absorption characteristic of the cement of which said stone is made. A limit in the high cost of said reinforcing board attached to a rear surface of the insulating board, and a limit in said brackets made in metal, that, connecting the three above said layers, will become a thermal bridge from the outside to the wall. On the other hand, for the industry of said artificial stones, the obstacle is to develop a product that may represent appearance close to the natural beauty of the marble, stones or bricks, and at the same time, light enough to install it on an insulation board. For the obstacle of the appearance above mentioned, German Patent No 5364 672 discloses a method to produce artificial stones using a mix of waste glass and resin. This procedure, that includes the exclusive use of waste or new powder glass, will leave on the surface an unnatural color because the glass is artificially colored. Japanese Patent No 6127458 provides also an artificial stone molded by injecting a composition of resin and mineral chips into a mold and after cured and demolded, polished, in order to show the minerals color. The limit on the result, appear on the polishing phase, that will expose, unprotected, the surface of the mineral, which can be affected by UV and the weather. Combining the weightlessness and the insulation characteristics of the foam material with those of decoration and stability of brick or stone is the biggest challenge.

Technical Solution

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. The recrystallized carbonate minerals are those that give the translucency feature to this beautiful stone called from the Ancient Greek (mármaros), “crystalline rock, shining stone”. The method of transfer durable features, such as hardness, shape, texture, translucency of the natural color of the stones, marble, bricks (terra cotta) on a soft insulating surface, to make it as a unique product, its use and application, is the object of this patent. The present invention includes the creation of a system of insulation modules having the appearance of dry stack or grout stone siding or grout brick or hollow tiles or roof tiles or any other shapes. The insulation system of the present invention includes a number of modules with substantial coordinated sizing under a criterion disclosed in this document.

Advantageous Effects

The present invention relates to panels with an external surface that simulates brick, stone, tile or marble and includes a method that may provide a kit of panels that, when installed on a surface including wall, floor or roof, without a need to cut or modify, said modules will fit any sizes of said surfaces, without showing where said modules are joining. Additionally includes methods to produce artificial cladding that includes grout between components, including stones, bricks or tiles, assembled as one body in a module that may be part of said kit. Furthermore, include method to produce said grout in independent color from the color of said components. Moreover includes methods to produce on said module, a controlled thickness of a layer of insulation in order to determinate desired R-value.

The Panel

PREFERRED MODE FOR CARRYING OUT THE INVENTION

Overview

The panel object of the present invention simulates genuine brick, stone, marble, slabs, tiles and so forth. The panel of the present invention may vary in shape, texture, color, and weight, depending on the sought after style (tile, brick, stone, marble slab, and so forth) and the purpose (decoration of a wall, or create a countertop for a vanity) chosen. The panel for the decoration of a building wall, for example, could have the appearance of a finished assembled stone-wall and generally will comprise an interlocking system for the assembly. In one embodiment, the panel may simulate repeating brick or ceramic tile patterns.

The dimensions of the panel, ranges, for example from side to side the panel may range from about 1′ (1 foot or 30.48 cm) by 1′ to the width of the wall, but for convenience, is preferable a dimension that is easy to be managed by one person, for example 4′ (˜121 cm) wide by 2′ (60.96 cm) feet high.

The thickness of the panel may depend on the shape of the decoration and the purpose of the installation that, for example, may also include the thermal insulation of the wall. In case one chooses to simulate a flag-stone and wants to reach a thermal resistance of 25R-value of the wall, the total thickness may range between 5″ (˜12.7 cm) and 8″ (˜20.32 cm).

The manufacture of the external layer of the panel will depend on the platform being simulated. For example, in the case of flag-stone, it will be achieved by a combination of two different dust marble, pink corallo and White Carrara, while gray occhialino may be used for the grout color.

The Panel

With reference to FIGS. 1A and 1B, a panel 100, according to one embodiment of the present invention, may include a body 10, a top layer 101 which provides a viewable surface, a base layer 103 which may provide structure and/or insulation, and a middle layer 102 which may provide the connection between the top layer 101 and the base layer 103.

The top layer 101 may include an external or first surface 134, an internal or second surface 135 and sides 137 extending from the first surface 134 to the second surface 135. In the case of a rectangular panel, the external layer would include 4 sides, in a triangular panel, 3 sides, and so forth.

The top layer 101 may be made of one film/coat or of multiple films/coats (i.e. multi-film or multi-coat). The term “multi-film” or “multi-coat” as used herein, refer to an overlapping of several or many films or coats as shown in FIG. 1B: an external substantially transparent film/coat 116, a film/coat of natural granules 117, and a support film/coat 118. Although FIG. 1B illustrates 3 films, it should be understood that less or more than 3 films are possible.

The external coat 116 of the top layer 101 may be a substantially transparent film 116. The external substantially transparent film 116 may be made of a substantially transparent polymer, such as an acrylic resin, an unsaturated polyester resin, an epoxy resin, a melamine resin, a urethane resin, as described herein below. The external film 116 forms the first surface 134 of the top layer 101.

The natural granule film 117 lies directly beneath the external film 116. The natural granule film 117 may be made of inorganic fillers. Natural granules includes one or more additives of an inorganic filler, a cross-linking agent, a cross-linking accelerator and a pigment, in addition to the above described components. Specific kinds of the inorganic fillers above are not particularly limited. Examples of these inorganic fillers may include one or more of calcium carbonate, silica, metal hydroxide, minerals and alumina. Specific diameter sizes of the inorganic fillers above are not particularly limited and it can be use any particle sizes ranging from 0.05 mm to 20 mm.

The support film 118 may provide mechanical support to the external film 116 and the granule film 117 as well as provide background color. The support film 118 may be made of binders and/or fillers as described herein below. The support film 118 forms the internal or second surface 135 of the top layer 101.

The top layer 101 of the panel may simulate any genuine brick, stone, marble, granite, slab, tile desired and any desired pattern of bricks, stone, marble, granite, and tiles.

The middle layer 102 provides the connection between the top layer 101 and the base layer 103. The middle layer 102 may be made of a foaming binder such as polymer foam or cellular cement.

The base layer 103 is the layer that provides the insulation and/or structure. The base layer 103 may be made of any suitable material that provides insulation and may also provide structure to the panel, such as extruded polystyrene, expanded polystyrene, polyisocyanurate, polyurethane, cementitious foam, cellular glass, vermiculite and so forth. The base layer 103 includes a first face that faces the second surface of the top layer 101, and a second face 108 that faces the substrate of the structure being covered. The second face 108 may include one or more ventilation channels 105 as illustrated in FIG. 4. The transversal cross section of the ventilation channels may take any suitable shape, such as “T” or “V” shapes.

The panels 100 may take any suitable shape, such as rectangular, circular, triangular, square, and so forth.

The panels may include an interlocking system to interlock with other panels, or they may be devoid of interlocking system.

As illustrated in FIG. 10, the panel may also include a mesh 780 connected to the second surface of the support film 118, which may be made of metal or a fiber that is non-combustible. This optional mesh will reinforce the structure of the layer 101 and will function as a place for mechanical support of the panel if the insulation layer 103 is not required or to prevent the detachment of the panel from the support (wall), if, in case of fire, the layer 103 the primary place of mechanical support of the panel, will melt.

The top layer 101 provides the looks of the panel, the middle layer 102 and the base layer 103 may be made of the same or different materials. The base layer 103 may provide insulation and/or structure, while middle layer 102 provides the connection between the top layer 101 and base 103 layer. As illustrated in the embodiment of FIGS. 11A-B, the middle layer and the base layer may not be necessary if, for example, insulation is not required. In FIGS. 11A-B the panel 1100 consists of only the top layer 1101 (FIG. 11A) or the top layer 1101 and a mesh 1178. In FIGS. 11A-B the top, multi-film layer comprises the substantially transparent coat 1160, the granular coat 1170 and the background color coat 1180. In FIG. 11B, the mesh 1178 is connected to the second surface of the background color coat 1180.

Double Interlock System

In the embodiment illustrated in FIGS. 1A and 1B, the perimeter of a modular panel 100 may include interlocking systems. In the case of a modular panel 100, at least two sides of the external layer 101 may include attachment mechanism 115. The attachment mechanism 115 are disposed on a side of the panel 100 to interlock with a corresponding attachment mechanism on an adjacent panel and retained.

Each modular panel 100 may include flanges 115 and pockets 16 formed about the sides of the body 10. The flanges 15 and pockets 16 are adapted to fit together with mating flanges and pockets of an adjacent panel.

With reference to FIG. 6, in the case of modular panels 100 a,b with an insulating layer 103, the bottom surface of pocket 16 may be formed by the insulating layer (see FIG. 6A). When the modular panel 100 a is attached to a substrate, the panel may be secured by screws 700 through the bottom surface of pocket 16 to the substrate. When the flange of a neighboring panel 100 b interlocks with the pocket 16 of the panel 100 a screwed to the substrate, the flange of the neighboring panel 100 b will hide the screw 700. Both module 100 a,bs, will have a double interlock and will hide the screws 700 that will attach one of the said modules 100 a to the substrate, and hold in place the next one 100 b (see FIG. 6A and FIG. 6B).

Interlock with Expansion Joint System

In another embodiment, illustrated in FIG. 4 and FIG. 7A-E, the perimeter of the top layer 101 may include interlocking flanges 115 to connect to adjacent panels 100 a,b as explained above and pockets 16. The profile of the base layer 103 may include a dovetail shape 122. Kind of usable shape in preparing said dovetail shapes are not particularly limited. Examples of such shape, which are usable herein, may include an, “T”, “V” shape (see FIG. 4 and FIG. 7). In this case, the pocket 16 lacks a bottom surface, as the base layer 103 does not extend. A connector 106 is provided for each direction and having a dovetail shape complementary to the dove tail shape of the base layer 103. The connector includes a first face 107. As such, the connector 106 may be positioned next to the base layer 103 as shown in FIGS. 7A-C, and the first face 107 of the connector 106 will serve as the bottom surface of the pocket 16. Once secured, through screws 700 for example, to a substrate (floor, wall or pitch of the roof and so forth), will lock the module 100 a to the previously mentioned support (see FIG. 4). The next module 100 b, joining to said connector 106 with its interlocks, will cover any joints (screws 700) on the connector 700 and engage onto with the module 100 a already locked to the support and leaving a gap 701 between the interlocks (see FIGS. 7D-E). Said connector 106, includes an exposed face 107 and in contact with said interlocks of external multi-films layer of said module. Said exposed face 107, may, in one embodiment, be covered with the same compound used to create grout as described herein below. Said connector 106 acts both as an expansion joint and joint the interlocks of the modules 100 a,b connected, covering said gap 701 and maintaining the continuity of said grout of the modules 100 a,b.

Method of Producing the Panels

The methods for producing the panels of the present invention will be now described with reference to FIGS. 1A, 1B, 2, 3, 4, 5, 6A, 6B, 8 and 9.

FIG. 8 shows a general flow chart of the method in accordance to one embodiment: (a) forming a substantially transparent coat (801); (b) dispose one, two or three of: a composition comprising natural granules and/or color onto the substantially transparent coat (802 a), and/or clusters of clusters of compositions comprising natural granules and/or color onto the substantially transparent coat (802 b), and/or slices of a mass of clusters comprising natural granules and/or color onto the substantially transparent coat (802 c); (c) dispose a support and/or background layer onto the composition of natural granules and/or color (803); (d) dispose a binder onto the layer of support and/or background color (804); and (e) dispose a base layer onto the binder (805).

The present invention includes, in one embodiment, a method to produce the panel 100 of the present invention. The method for the production of said panel 100 may be divided into phases, which will produce at least three layers of which the panel (or modules) is/are comprised: a top multi-films layer 101, a middle layer 102, and a base layer 103. An optional step of adding grout (806) is also depicted between steps 803 and 804.

The method to produce a panel of the present invention includes the use of a mold 1200. With reference of FIG. 12, the mold 1200 comprises a continuous side wall 1201 forming the perimeter of the mold 1200 and a base 1205. The interior surfaces of the walls and the base 1205 form the mold's cavity 1202. The interior surface of the base forms the cavity's floor.

The floor of the mold cavity 1202 will create the shape or silhouette of the external multi-film layer 101 of said panel. Said mold 1200 can be made in different material: semi-hard, soft or hard, perennial or not perennial. Said floor of the mold's cavity 1202 includes a shape or silhouette. Said shape may include interlocks 115 and pockets 16 on the top multi-films layer 101 of said panel that will match and connect multiple modules (see FIG. 5). Said mold 1200 can be closed with a counter mold or opened, without a counter mold. Said mold includes a case to hold one or more molds. If it is intended to produce the above-mentioned system, the molds may need to be created at least four molds, that are able to produce modules having dimensions according to said criterion and interlocks 115, on two or more sides distributed asymmetrically (see FIG. 1A). The mold 1200 may be made of any suitable materials (metal, plastic silicon, wax etc.). The interior bottom surface of the mold 1200 will replicate the negative shape of the wanted configuration of the panel. For example, in the case of a flag-stone or brick, the bottom surface of the mold 1200 may present depressions, and textures for the correspondent stones or bricks and ribs 1203 separating the depressions for forming the groves in between the flag stones.

First Phase: The Top Layer

The top, multi-film or multi-coat layer 101 may be created with at least three different methods.

In FIGS. 8 and 9, steps 802 and 902 illustrate three options: 802 a/902 a, 802 b/902 b and 802 c/902 c respectively. Each option represents the three methods described herein below. It should be understood that anyone or any combination of these three options may be used. For example, one may dispose cluster of compositions and slices of a mass of clusters.

The first two steps are common to all three methods:

-   -   1. Spread a release-agent on the interior surfaces of a mold         (surfaces within the cavity of the mold), to form a         release-agent coat.     -   2. Spread onto the release-agent coat, a coat of a substantially         transparent polymer to form the substantially transparent coat         116 of the top layer 101 (see 801/901).

The use of a release agent facilitates the removal of the panels from the mold. However, it should be understood that this step may not be necessary. The release agent may include different compositions like liquid, gel, and dust. The shape, the form and the texture of the external surface 134 of the top layer 101 of the module 100, will be influenced by the release agent.

Kind of usable substantially transparent polymer in preparing said substantially transparent coat 116 are not particularly limited. Examples of such substantially transparent polymer, which are usable herein, may include one or more of an acrylic resin, an unsaturated polyester resin, an epoxy resin and a melamine resin, a urethane resin. Specific kinds of said acrylic resin are not particularly limited. For example, a polymer of one or more acrylic monomers of methyl (meth) acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, benzyl (meth)acrylate and glycidyl (meth)acrylate may be used. Kinds of said unsaturated polyester resins are also not particularly limited. For example, a polyester resin having an acid value of 5 to 40 and a weight average molecular weight of 1,000 to 5,000, which is prepared through a condensation reaction of an unsaturated dibasic acid or a mixture of said dibasic acid and saturated dibasic acid with a polyhydric alcohol, may be used. At this time, the process for preparing said polyester resin is not particularly limited. For example, it may be prepared by a method which comprises a step of mixing said dibasic acid and the like with said polyhydric alcohol in a specific ratio (for example, moles of alcoholic hydroxide group/moles of carboxylic group=0.8 to 1.2), subjecting said mixture to a condensation reaction at a temperature of about 140 to about 250° C. under an inert gas flow such as carbon dioxide gas and/or nitrogen gas with removing resulting water and slowly increasing the temperature depending on degree of proceeding the reaction. Examples of unsaturated dibasic acids or saturated dibasic acids as used above may include maleic anhydride, citraconic acid, fumaric acid, itaconic acid, phthalic acid, phthalic anhydride, isophthalic acid, terephthalic acid, succinic acid, adipic acid, sebasic acid and/or tetrahydrophthalic acid, and the like.

If necessary, said polyester resin may further comprise a monobasic acid such as acrylic acid, propionic acid and/or benzoic acid; or polybasic acid such as trimellitic acid and/or benzene tetracarboxylic acid. In addition, kinds of usable epoxy resins are also not particularly limited. For example, a bifunctional or multifunctional epoxy resin may be used. Examples of said bifunctional or multifunctional epoxy resins may include one or more of a bisphenol A epoxy resin, a bisphenol S epoxy resin, a tetraphenyl ethane epoxy resin and a phenol novolac epoxy resin.

(i) First Method of Making the Top Multi-Film Layer 101

-   -   1. Spread a release-agent on the interior bottom surface of the         mold, to form a release-agent coat.     -   2. Spread onto the release-agent coat, a coat of a substantially         transparent polymer to form the substantially transparent coat         116 (801/901).     -   3. Overlay or dispose a composition comprising natural granules         and/or color onto the substantially transparent polymer coat         116, preferably before it hardens, to form a film or coat of         granules and/or color 117 (802 a/902 a).

The granular/color layer may be made of desired color pigments, and may include natural granules to provide a more genuine look. The color layer may pre-made.

Natural granules that may be used in this method or any of the methods described below includes one or more additives of an inorganic filler, a cross-linking agent, a cross-linking accelerator and a pigment, in addition to the above described components. Specific kinds of the inorganic fillers above are not particularly limited. Examples of these inorganic fillers may include one or more of calcium carbonate, silica and silica derivatives, metal hydroxide, minerals, glass and alumina. Specific sizes of the inorganic fillers are not particularly limited and it can be use any sizes ranging from 0.05 mm to 20 mm in diameter. For granular look, bigger sizes, for a smoother look, smaller sizes. The nuance-color can be laid, using different colors, layer by layer or stone by stone: one may lay the color layer in a non-uniform way, or stone by stone so as to imitate the original brick, marble and so forth.

The following are the ingredients that can be used to prepare different colors that may be used:

Nuance-Color for flag-stone: Pink corallo marble, white Carrara, gray occhialino dust (size 0.7-1.2 mm)

Nuance-Color for brick: black ebano marble dust (size 0.7-1.2 mm)

Base-color for flag-stone: a mix in ratio in weight of 1 to 10 in dust of pink corallo and white Carrara (size 0.7-1.2 mm)

Base-color for brick: red. Verona marble dust (size 0.7-1.2 mm)

(ii) Second Method of Making the Top Multi-Film Layer 101

Materials:

Prepare granular mixtures in ratio of 1 to 6 of clear epoxy and marble dust of one, two, three or more different color, like Pink corallo marble, white Carrara, gray occhialino dust (diameter size 0.7-1.2 mm). Create granular clusters of one or different colors and sizes with the mixtures.

Optionally, prepare a liquid mixture of a clear epoxy and color pigments.

Steps:

-   -   1. Spread a release-agent on the interior bottom surface of the         mold, to form a release-agent coat.     -   2. Spread onto the release-agent coat, a coat of a substantially         transparent polymer to form the substantially transparent coat         116 (801/901).     -   3. Fill the mold with the granular clusters in a uniform or         no-uniform way (802 b/902 b). If a liquid mixture is provided,         the liquid mixture may be interposed in the gaps between         granular clusters. This liquid mixture may be used to form the         veins of marble or granite. The granular clusters with or         without the liquids will form the granular coat 117.

This second method may be used to replicate granite (if the diameter of the clusters are in range of 1 mm to 20 mm in diameter) and marble (if the diameter of the clusters are sized above 20 mm in diameter).

An optional polishing phase with a final coat of acrylic resin will lighten up the nature of the vein.

(iii) Third Method of Making the Top Multi-Film Layer 101

This method may be suitable for creating slabs, which can be used to create table-tops, countertops, tomb stones, and so forth. This third method may give a similar result as the above method 2 without a need to add the polishing phase with the final coat of acrylic resin.

Materials:

Prepare one, two, three or more mixtures in ratio of 1 to 6 of clear epoxy and marble dust of one or different colors, like Pink corallo marble, white Carrara, gray occhialino dust (size 0.7-1.2 mm). Create clusters of different color and sizes with the mixtures.

Optionally prepare a liquid mixture of clear epoxy and pigments color

-   -   3. Create a granular mass, for example by laying the clusters of         one or different colors one on each other, in a no-uniform way,         optionally interposing the liquid mixture in the gaps between         the clusters.

Steps:

-   -   1. Spread a release-agent on the interior bottom surface of the         mold, to form a release-agent coat.     -   2. Spread onto the release-agent coat, a coat of a substantially         transparent polymer to form the substantially transparent coat         116 (801/901).     -   4. Cut the mass of clusters in slices. If liquid mixture is         used, then every slice will show veins marble like or granite         like (it will depend on the diameter size of the clusters).     -   5. Position the slices onto the substantially clear coat in the         mold, in a uniform or a no-uniform way to form the granular coat         117 (802 c/902 c).

Method 3 can be used to replicate granite (if the diameter of the clusters are in range of 1 mm to 20 mm) and marble (if the diameter of the clusters are above 20 mm in diameter).

In option polishing phase with a final coat of acrylic resin will lighten up the nature of the vein.

The final step, common to all of methods 1-3 is to overlap a film or coat of mechanical support and/or of background color, preferably, before the granular coat hardens, to form the support layer 118, which may provide background color (803/904). This support layer 118 may be a mixture, preferably 1 to 3 in weight, of a clear epoxy and a base color.

The film 118 of mechanical support and/or of background color may be made of a single component or a mixture of components. Said components may include binders and fillers. Said binders include, in measure of weight of 15% to 35%, of a substantially transparent polymer. Kinds of usable substantially transparent polymer in preparing said binders are not particularly limited. Examples of such substantially transparent polymer, which are usable herein, may include one or more of an acrylic resin, an unsaturated polyester resin, an epoxy resin and a melamine resin, a urethane resin. Specific kinds of said acrylic resin are not particularly limited. For example, a polymer of one or more acrylic monomers of methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, benzyl (meth) acrylate and glycidyl (meth) acrylate may be used. Kinds of said unsaturated polyester resins are also not particularly limited. For example, a polyester resin having an acid value of 5 to 40 and a weight average molecular weight of 1,000 to 5,000, which is prepared through a condensation reaction of an unsaturated dibasic acid or a mixture of said dibasic acid and saturated dibasic acid with a polyhydric alcohol, may be used. At this time, the process for preparing said polyester resin is not particularly limited. For example, it may be prepared by a method which comprises a step of mixing said dibasic acid and the like with said polyhydric alcohol in a specific ratio (for example, moles of alcoholic hydroxide group/moles of carboxylic group=0.8 to 1.2), subjecting said mixture to a condensation reaction at a temperature of about 140° C. to about 250° C. Under an inert gas flow such as carbon dioxide gas and/or nitrogen gas with removing resulting water and slowly increasing the temperature depending on degree of proceeding the reaction. Examples of unsaturated dibasic acids or saturated dibasic acids as used above may include maleic anhydride, citraconic acid, fumaric acid, itaconic acid, phthalic acid, phthalic anhydride, isophthalic acid, terephthalic acid, succinic acid, adipic acid, sebasic acid and/or tetrahydrophthalic acid, and the like. Examples of polyhydric alcohols may include ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, polypropylene glycol, 1,3-butylene glycol, hydrogenated bisphenol A, trimethylol propane monoarylether, neopentyl glycol, 2,2,4-trimethyl-1,3-pentanediol and/or glycerine, and the like. If necessary, said polyester resin may further comprise a monobasic acid such as acrylic acid, propionic acid and/or benzoic acid; or polybasic acid such as trimellitic acid and/or benzene tetracarboxylic acid. In addition, kinds of usable epoxy resins above are also not particularly limited. For example, a bifunctional or multifunctional epoxy resin may be used. Examples of said bifunctional or multifunctional epoxy resins may include one or more of a bisphenol A epoxy resin, a bisphenol S epoxy resin, a tetraphenyl ethane epoxy resin and a phenol novolac epoxy resin. Furthermore said film of mechanical support and of background color include, a foamed material and/or natural granules. Examples of said foamed material include foamed polymers and foamed cementous materials with inorganic fillers. Specific kinds of cementous materials are not particularly limited. Examples of these cementous materials may include one or more of cellular concrete Gypsum (GRG) and so on. Moreover, said fillers of the above mixture, includes natural granules in measure of weight of 65% to 85%. Natural granules includes one or more additives of an inorganic filler, a cross-linking agent, a cross-linking accelerator and a pigment, in addition to the above described components. Specific kinds of the inorganic fillers are not particularly limited and they can be used in any particle sizes ranging from 0.05 mm to 20 mm in diameter. Examples of these inorganic fillers may include one or more of calcium carbonate, silica and silica derivatives, metal hydroxide, minerals, alumina and fire retardant additive, flame retardant additives or incombustible additive.

Grout

If grout is desired in between the bricks or marble stones, to have the color of said grout independently from the rest of the stone, one may proceed as follow:

To recreate grout, a mold, such as the mold 1200 depicted in FIG. 12, may be provided with ribs 1203 extending from the cavity's floor. The top surface of the ribs 1203 protruding from the floor of the mold's cavity 1202 may be cleaned or scraped from the materials that were laid in the previous steps (methods 1-3). Alternatively, the top surface of the ribs 1203 may be masked, and the mask removed thereby leaving a clean surface on the ribs 1203. The materials/compositions used to create said mask are not particularly limited. Examples of these materials may include one or more metals, papers, plastic, wood, paint and composites.

1. Clean the ribs 1203 of the mold 1200 where the shape represent the grout.

Specific processes of how to clean said mold where the shape represent the grout are not particularly limited. Examples of these processes may include scraping out the excess of the materials above described to create said external multi-films layer in the present method.

2. Overlay a composition comprising the color of the preferred grout on the top surface of the ribs 1203 to create said external multi-films layer in the present method (806/907). For example, a mix in ratio 1 to 4 in weight of clear epoxy with the grout (grey occhialino marble dust (size 0.7-1.2 mm)) and lay it on the ribs 1203; allow the layers to combine and leave it until it cures.

Second Phase: The Base Layer 103

The second phase relates to the preparation of the base layer 103. Kind of usable material in preparing said base layer are not particularly limited. Examples of such materials, which are usable herein, may include one or more of an insulating and a structuring material. Specific kinds of said insulating material are not particularly limited. For example extruded polystyrene, (XPS). Expanded polystyrene (EPS) Molded expanded polystyrene (MEPS), polyisocyanurate, polyisocyanurate insulating material in structural insulated panels (sips) polyurethane, cementitious foam, cellular glass, yermiculite, may be used. This base layer 103 includes a shape or silhouette. The base layer 103 includes a first surface or face that is adjacent to the inner or middle layer, and a second surface or face 108 and functions as back to the module, which is in contact with the support (for example wall, roof, etc.). Said silhouette includes a number of ventilation channels 105. Said ventilation channels 105 have a shape. (See FIG. 2). Kinds of usable shape in preparing said ventilation channels are not particularly limited. Examples of such shape of ventilation channels, which are usable herein, may include an interlocking dovetail, “T”, “V” shape 105 may be used (see FIG. 4). The face 108 of layer 103 faces the structure. Said channels 105 may be configured to receive components 104 capable of merging to said channels including an interlocking clips 104 (see FIGS. 2 and 3). Kinds of usable material in preparing said components are not particularly limited. Examples of such material like, polymeric structural material and metal may be used. Said components 104 may be independently secured to the support of the structure, such as a house. The panels may then be secured to the components 104 by inserting or sliding the components 104 into the channels 105 which will lock the module to the same support (see FIG. 3). Said silhouette of said base layer 103, comprises a different combination of profiles. The present invention includes multiple systems to install said module to the support (for example wall, roof, etc.) According to the system chosen, the base layer may possibly have different profiles of said silhouette.

Third Phase: Assembly of the Base Layer 103 to the Top Layer 101

The third phase includes the assembly of the base layer 103 already prepared, to the top multi-films layer 101, through the creation of the middle layer 102 (see FIG. 1). The assembly includes a layering of foaming or non-foaming binder directly on the second surface of the multi-films layer 101 while is still in the mold (804, 905). Kind of usable foaming binder to assemble the above layers are not particularly limited. Examples of such foaming binder, which are usable herein, may include Polymer foam, cellular cement. The base layer 103 is then disposed onto the binder (805, 906).

To speed up the production, it is possible to use the middle layer 102 as a counter-mold for the curing time of the external multi-films layer, as illustrated in FIG. 13B. In order to proceed in this manner, a second mold 1300 that has the shape of the middle layer 102 and fits within the first mold 1200 can be used. The foaming or non-foaming binder that makes the middle layer is poured into this second mold 1300. The base 103 is then placed on top of the middle layer 102 before is cured. After the middle layer 102 is cured and bound to the base layer 103, the middle layer 102 with the bound base layer 103 is demolded from mold 1300 (as shown by the arrow in FIG. 13A) and placed on the top the multi-films layer (i.e. on top of the layer 118) during the multi-film layer 101 curing time, as shown in FIG. 13B. The first mold 1200 is thereby closed with the middle layer 102 bound to the base 103, and the external multi-films layer becomes a binder to the middle layer 102.

Another option instead of a binder is to increase the volume of the grout or the background layer. This may be achieved by preparing a composite in a ratio (in weight) of about 1 of clear epoxy to 4 of a mixture, the mixture having a ratio of about 1 to 1 in weight of grout (grey occhialino marble dust (diameter size 0.7-1.2 mm)) or background color (marble dust (size 0.7-1.2 mm)), with micro balloon of glass (size between 0.3-3 mm) or silica fume, and lay this composite on the granular film 117, and cover the composite with the base of polystyrene 103 and close firmly the lid of the mold until it cures.

Furthermore, to speed up the curing time of the different layers, another optional phase may be to expose the different layers to a temperature in the range of about 50 C.° to about 150 C.°. This heat may be applied by inserting the mold in an oven, or may be applied to the bottom of the mold (with a heating element, heating lamp, heated air and so forth), or to the top of the mold (with a heating element, heating lamp, heated air, and so forth), or to the inside of the mold (heated air, heating lamp, infrared rays, and so forth), and/or of the mold itself and/or the surrounding area during the process.

With reference to FIG. 10, in the preparation of the layer 101, a mesh (metal mesh or fiber fabric mesh such as carbon, glass or Kevlar™ or any other non-combustible material) could be added and immersed in the background layer (or in the grout if one is provided) while is still wet (not cured yet) in measure to exceed from the surface 137, an adequate braces or brackets that can be screwed to the support during the installation process.

KIT or SYSTEM

A kit or system according to one embodiment of the present invention includes a number of at least four modules of the present invention with substantial coordinated sizing under a criterion disclosed in the present invention. The use of said criterion is not particularly limited to said insulation system. It may include one or more of construction paneling and module, structure, furniture and so on. Said criterion is described as follows:

Given a positive integer number, the sum of a multiple of said given number with a positive multiple for each of the three following consecutive integers, is capable to suit any number positive integer, greater than or equal to three times the given number. According to this criterion, assuming 12 as the given number, the three following numbers will be 13, 14, and 15. The sum of the positive multiples of these four numbers will be able to reach any chosen positive integer number greater than 36 (3 times 12).

On Table 1 random positive integer numbers are reached using the above criterion. In the top row, “a” represents the given number (12), “x” represents the random number and n is a number used to minimize the multiple of the given number (12); in this table, “n” was chosen to be equal to 4. The numbers “a+1”, “a+2”, and “a+3”, represent respectively the consecutive numbers of 12 (13, 14, and 15). On said table 1, the above numbers “a” “a+1”, “a+2”, and “a+3”, represent possible different widths of the modules while “x” represent possible different widths of the surface where the modules will be installed. All the widths are expressed in inches. As it can be noticed, the criterion fulfills any random number (widths of surfaces) equal or greater than three times the given number; in this case, all widths greater than 36 inches.
